Solved last nights problems with the heater fitting, by drilling a couple of extra holes in the heater bracket (see picture).

Also used the heater as a template for drilling other holes (it meant drilling back to front with the pretty side of the GRP on the exit side of the hole, not recommended from a risk of cracking point of view but these holes are going to have big 'repair' washers around them so the aesthetics don't matter that much.


Also used a new 16mm hole saw (bought from that excellent real honest to god tool shop in Fulham called Grizards - a shop that is the opposite of chain DIY stores, they have everything and know what they are talking about, if I say "hand written receipts" you'll get the picture http://www.grizards.co.uk/) unfortunately the specified 16mm isn't big enough for the metal pipework so will need to 'fettle' that out tomorrow.

It doesn't yet feel like we are on the downhill stretch as we know there is months of work still to do, but we are making progress.
